What else can I help you with?
If two lines are not coplanar then they are neither intersecting nor parallel?
CorrectParallel lines as well as intersecting lines must be coplanar (in Euclidean geometry not quite sure about hyperbolic geometry...).Lines in space which neither are coplanar nor intersecting are called "skew"
Can two intersecting lines be non-coplanar?
No.
Are two intersecting lines are coplanar?
Yes.
Are vertical angles formed by two intersecting lines coplanar?
Yes. They're in the plane defined by the two intersecting lines.
Is intersecting lines always coplanar?
Yes. The two lines define a plane which they both belong to.
Difference between concurrent coplanar forces and non concurrent coplanar forces?
Concurrent coplanar forces have their lines of action intersecting at a common point, allowing them to be resolved using the parallelogram law of forces. Non-concurrent coplanar forces have their lines of action not intersecting at a common point, requiring the use of the triangle law of forces for resolution.
Are any two noncoplanar lines skew?
I guess they are. If they're parallel or intersecting, then they're coplanar.
How many planes can contain intersecting lines?
I'm not entirely certain what you're asking. Any pair of intersecting lines are of necessity coplanar, (assuming Euclidean geometry) though.
How many pairs of vertical angles are formed by 3 coplanar lines intersecting at one point?
Eight.
Do Coplanar lines are either parallel or intersecting?
Yes. Although, they could be coincident which may not be covered by either of these descriptions.
How many pairs of vertical angles are formed by 5 coplanar lines intersecting at one point?
20....or maybe 18
What is two lines in the same plane called?
Two lines in the same plane are called "coplanar lines." If they do not intersect, they are referred to as "parallel lines." If they intersect at a single point, they are simply called "intersecting lines."
